304 stainless steel plate products have strong corrosion resistance, for ordinary alkali solution and organic acid, inorganic acid have good corrosion resistance, it is a kind of high alloy steel, can 38 tube fitting resist air or chemical corrosion in the corrosive medium. Stainless steel surface is aesthetically pleasing and good corrosion resistance. It does not need to surface treatment such as electroplating, to give the surface of the stainless steel overall performance. One aspect of the steel, usually called stainless steel.

304 stainless steel tube in the welding needs pay attention to what aspects?

1. The distinction between bottom and cladding in welding process, with their respective applicable welding materials for welding.

2. In order to ensure the corrosion resistance of coating, the coating of the weld composition should be like the cladding steel components.

3. In the two layers together, in order to avoid the cladding will be the underlying diluted, make the corrosion resistance is reduced, thus the welding of the key is to deal with two layers of border area of welding, can be in the bottom of transition layer between the coating and the weld.

4. Heat treatment after welding of large thickness of stainless steel plate welded components, heat treatment after welding can eliminate the welding residual stress.

5. Pay attention to the heat treatment at high temperature, would amount to a cable on one side of carbon steel decarburization in body, lower the progress; While at the side of the stainless steel by carburizing and hardening is crisp, the impact toughness decreases, become a welded joint in danger of failure, it is not desirable.

Stainless steel pipe fittings can be divided into, the stainless steel tee, stainless steel flange, stainless steel head size, stainless steel elbow, stainless steel pipe cap, stainless steel sealing the top.

Iron and steel is how to distinguish between carbon content. Carbon content is brass tube fitting under 2% of the iron carbon alloy steel, carbon content over 2% is called iron. Steel is because there are both toughness and elasticity and rigidity, are widely used. Life encounters is steel, but with different people call. For stainless steel, regardless of the magnets on it or not, as long as meet the quality standards, are stainless steel.
